Abstract
In one embodiment, a medium voltage drive system includes at least one transformer and multiple power cell chambers each coupled to a transformer. The power cell chambers each may include a rectifier, a DC-link, and an inverter. Each power cell chamber can be separated into fixed and moveable portions, where the moveable portion includes the rectifier and the inverter and the fixed portion includes the DC-link. A power service bus can couple the fixed and moveable portions of each power cell chamber and couple in series groups of the plurality of power cell chambers.
